Guaibasaurus was a basal Saurischier is possibly one of the theropods, but sometimes also made to the Sauropodomorphen or Herrerasauriden. He possessed as Herrerasaurus and other early dinosaurs three fully developed and two atrophied fingers.

He reached a height of 1.2 meters, a length of 3 meters and a weight of 100 kg.

Bonaparte, Ferigolo and Ribeiro discovered him in 1999 in Brazil ( Caturrita Formation).

Bonaparte was released in 2007, that Saturnalia and Guaibasaurus are very closely related, and summarized them as Guaibasauridae. There were probably ancestors of the theropods.
